xbps from launchpad head branch has gained support for extended
pkg version matching, as specified in:
https://blueprints.launchpad.net/xbps/+spec/improved-version-matching
Now it's required to specify the operator(s) for required versions
in the depends files and "Add_dependency" option in build templates.
xbps-src now requires xbps utils 20091107.
